Atomic Radio Controlled Clock Instructions Congratulations on your purchase of this quality RC Wall Clock. Great care has been taken to design and manufacture your clock. Please read these instructions and keep them safe, as you may want to refer to them in the future. The clock’s time setting will occur automatically soon after the battery is inserted. The radio controlled mechanism tunes itself to the time signal broadcast by the official U.S. Atomic Clock in Fort Collins, Colorado also known as WWVB. Buttons Description REC – Receive Button, press this button to force the clock to search for the radio signal. SET – Manual Set Button, to set the time manually press and hold this button for 5 seconds until the hands start to move. Continue to press button until correct time is displayed. PMCE – Switch button for time zone selection (P): Pacific Time (M): Mountain Time (C): Central time (E): Eastern Time ON/OFF – Daylight Saving Time Switch, please always keep this switch ON. Residents in the states of Arizona and Indiana that observe Daylight Saving Time (DST) should keep in OFF position. How do I start the clock? Insert on “AA” alkaline battery (not included) into the compartment on the back of the clock, making sure that the polarities match those shown in the compartment. After the battery is inserted; you will see the second hand move clockwise to the 12 o’clock position. Within three minutes the hour and minute hand will move to one of three standby positions: 4, 8 or 12 o’clock. The clock will search to receive the radio signal. If the signal in your area is strong; the clock will set itself within three to ten minutes. If the signal is weak or the clock is unable to receive the signal the hands will not move. The clock will try to receive the signal once an hour for the first 24 hours. Due to atmospheric conditions the signal is often strongest between midnight and 4AM. When the clock has found the signal and finished setting itself it will seek out the signal once each day to maintain its accuracy. After 24 hours if there is no signal the clock hands will move but will not go to the correct time. To conserve battery life, the clock will then start to search for the signal every second hour on the odd hours (1 o’clock, 3 o’clock etc). If there is no signal the clock should be moved to another location in order to receive the signal. The antenna is directional so one location will probably work better than another. What should I do if my clock will not synchronize at all? Check the battery lifetime and if necessary try a different battery. If nothing else works take the clock outside on a clear night and remove the battery. Power it up again by reinserting the battery to force it to search for the signal again. If the clock works outside but not inside you probably have a local interference problem in your house or building. If the clock not works outside at night it is probably due to rough handling, check to see if any battery contact loosening or hands attachment off and let qualified repairmen take care of it. What can I do to improve signal reception? If you plan to use this clock in a concrete or metal building, reception will be improved if the clock is placed near a window, with any curtains or blinds open. Do not place the item too close to electrical appliances such as televisions, microwaves, speakers, and computers or fax machines. Many natural and man-made items can block or interfere with radio signal reception. These include tall buildings, airports, mountains and valley and electrical items such as high voltage cables, traffic lights or neon lights. Bad weather can also affect the signal. What do I need to do when we gain or loss an hour? Nothing! The time will switch between Greenwich Mean Time and Daylight Savings Time automatically when the signal is received. How should I care for my clock? Replace the battery every year or when the clock loses its ability to receive the radio signal. Keep the clock clean and dry. A soft cloth should be used regularly to keep the product dust free. Do not use any corrosive cleaner or chemicals on the clock. Always store the clock without a battery whenever it is not in use.
